Benthic diatoms

An analysis of the taxonomic diversity of benthic diatoms was carried out for near-shore biotopes of Crimea with different content of trace metals and organic pollutants (PCBs, PAHs, DDTs). Taxonomic distinctness indices such as average taxonomic distinctness, AvTD (Δ+) and variation in taxonomic distinctness, VarTD (Λ+) were used for evaluation of the hierarchical structure of diatom taxocenes of two intact sites (Dvuyakornaya Bay and Cape Fiolent) and two heavily polluted water areas (Sevastopol Bay and Balaklava Bay).

Nutrients in sediment regulate benthic algal assemblages in the tropical Tri An reservoir of Vietnam
This preliminary data set demonstrates the use of benthic algae as precise biological indicators for a measure of the ecological integrity of an aquatic ecosystem and contributes to the further study of benthic environments in tropical regions.

The impact of liquid wastes from a city sewage/ waste water on the benthic diatoms in flowing waters has been studied for a period a year (May 2015- April 2016). Water and algal samples were analyzed seasonally intervals at five sites along the course of the rivers Ganga, Allahabad.

In the present study, the Biological diatom index (BDI) and the Trophic diatom index (TDI) were calculated for the assessment the ecological status and the water quality of the Sai Gon river in comparison with the physico-chemical variables. In addition, a multivariate method was used to elucidate the main environmental variables driving the diatom community. A total of 87 diatom species were identified and used to calculate the diatom indices.

The shoreline benthic diatoms of Asartepe Dam Lake were identified from different habitats (epipelic, epiphytic, and epilithic) at 7 sampling stations between April 2003 and June 2004. In the investigation, a total of 93 taxa were identified. Of those, Cymbella affinis Kütz.

Phytoplankton and planktonic centric diatoms of Lake Stechlin have been extensively studied, while attached diatoms have received much less scientific interest. In the present study, the composition of benthic diatoms and their diversity metrics were determined and compared along the shoreline of the lake in spring 2013 and autumn 2014.
